Pintsch Aktiengesella corporation Application May 19, 1932, Serial No. 612,312, and l in Germany December 10, 1931 6 Claims.

This invention relates to illuminating lamps and is particularly although not exclusively applicable to lamps for railway signal installations ofthe kind which are capable of being moved up post, e. g. by sliding on rails.

The main feature of the invention resides in the fact that all the gas carrying parts comprising the complete burner arrangement (the gas container with valve, pipe, pressure regulator, burner and so on) are united with a supporting member which is adapted to be mounted in the interior of the lamp. The supporting member with the burner arrangement thereon may be inserted in and withdrawn from the casing as a unitary whole. As a result of the formation of such a unit, the necessity for a flexible tube or pipe between the gas container and burner is avoided. Moreover the mounting of the cornplete burner arrangement in the lamp is simplied. The complete illumination arrangement may be taken out of the lantern casing and tested in operation without having to disconnect the individual parts. Furthermore, the arrangement permits the light source to be adjusted exactly inside the lantern while the gas container is attached. This last named advantage is especially of importance in railroad signal lamps because such signal lamps are usually provided with parabolic mirrors which require an exact adjustment of the light source with respect to the focal point.

In order that the invention may be clearly understood and readily carried into eiect, it will Vnow be more fully described with reference to the example illustrated in the accompanying drawing, in which Figure 1 is a front elevation of the lamp, partially in section,

Figure 2 is a side elevation thereof, also partially in section, and,

Figure 3 is a plan view of the lamp, the top having been removed.

The gas container 1 with valve 2 is connected by a pipe 3 with the pressure regulator 4, to which the burner 5 is connected. The individual members of the constructional group are removably tted on a supporting member, e. g. a connecting plate 7. This plate is adapted to be mounted within the casing of the lamp and preferably on the wall of the casing which carries the hanging shoe 13 of the lamp. In this way heavy stresses on the casing of the lamp itself are avoided and the casing may be of thinner sheet material than is usually possible.

An Outrigger 8 of the plate 7 has a fork-like connecting piece 9 which embraces the valve 2 of the gas container. The pipe 3 terminates in the connecting piece 9 which is provided with an opening, and there is a corresponding opening in the valve 2, so that when the valve 2 is pressed against'the connecting piece 9 by means of the lstirrup 10, a gas-tight connection is brought about.

The connecting plate 7, and the casing wall which carries it, have elongated holes 11 which cross one another and through which the fixing bolts 12 are passed. In this manner a precise adjustment of the internal device as regards the focal position of the heated body is made possible. Lamps of this type may be provided with any suitable lens but, as mentioned above, they are usually provided with parabolic mirrors, such as those shown in Fig. 2. It is immaterial what type of directing means is used, but it is important that means be provided for adjusting the burner with regard to the focal position. This is accomplished in my arrangement without disturbing the connections of the complete burner arrangement.

For the damping of oscillations of the internal device, there can also be provided a resilient insertion, e. g. sheet of felt, a leaf spring or the like between gas container and lamp base plate.

The constructional group 1 to 5 and 7 can, after removal of the sheet metal underpart 6, which is detachably fastened on the lamp by any suitable means, be taken out downwards or conversely it can be inserted from below.

Preferably the casing which encloses the constructional group is provided on its under side with an auxiliary foot (strrup) 14 which is capable of being extended in a direction parallel to the standing surface in order to increase the stability when it is desired to rest the lamp on its base. The lamp shown, as prescribed by railway regulations, is bevelled at one side near the bottom.

What I claim is:

1. An elevatable signal lantern comprising a casing, a burner unit including a gas container within said casing, a supporting member, means for mounting said supporting member within said casing, said burner unit being mounted on said supporting member, whereby said supporting member and burner unit comprise a unitary whole which may be withdrawn from and inserted in said casing as such, said means making provision for horizontally and vertically adjusting the position of the burner in said burner unit with respect to the focal point.

2. An elevatable signal lantern comprising a casing, a gas container, a gas valve on said container, a gas conveying pipe, a pressure regulator, a gas burner, a supporting member, means for mounting said supporting member within said casing and for adjusting its position therein, said gas container, gas valve, gas conveying pipe, pressure regulator and gas burner being mounted on said supporting member.
